Abstract: A method includes error encoding data to produce a plurality of data slices. Metadata is determined for a data slice of the plurality of data slices. The metadata is stored in a metadata storage tree. The data slice is stored in a slice storage location indicated by the metadata. Based on determining to access the data slice, the metadata for the data slice is accessed in the metadata storage tree to determine the slice storage location for the data slice, and the data slice is accessed in the slice storage location based on determining the slice storage location for the data slice via accessing the metadata storage tree.

Abstract: A method for execution by one or more computing devices of a storage network includes generating an audit record data file regarding the execution of a data access request associated with a transaction within the storage network, where the transaction is associated with encoded data slices. The method continues with generating an audit object data log that includes at least the audit record data file and storing the audit object data log in at least one memory of the storage network. The method continues retrieving, from the at least one memory, the audit record data file of the audit object data log based on the information associated with the transaction. The method continues auditing the transaction for storage network operational compliance based on at least the audit record data file.

Abstract: A method includes receiving data for storage and encoding the data to produce a plurality of data slices. Metadata is determined for a data slice of the plurality of data slices. The metadata is stored in a metadata storage tree. The metadata storage tree is stored via a first plurality of memory devices of a first memory type. The data slice is stored in a slice storage location in a second plurality of memory devices of a second memory type. The slice storage location is indicated by the metadata. The first memory type has a higher performance level than the second memory type based on a utilization approach.

Abstract: Apparatus for tiered storage of data in a storage network. In an example of operation, a computing device receives a data object for storage and forwards the data object for storage in a first plurality of memory devices of a first memory type. The computing device determines a system level storage efficiency for the data object based, at least in part, on a data attribute associated with the data object. The computing device further selects, based at least in part on the system level storage efficiency preference, a second plurality of memory devices comprised of a second memory type. The computing device determines error encoding parameters based on the second plurality of memory devices, retrieves the data object from the first plurality of memory devices, and encodes the data object with the error encoding parameters to generate a plurality of encoded data slices for storage in the second plurality of memory devices.

Abstract: A method includes determining a plurality of identifiers based on a data retrieval request. Integrity information is generated based on determining the plurality of identifiers. Stored integrity information corresponding to the data retrieval request is compared with the integrity information. When the stored integrity information compares unfavorably with the integrity information, corruption associated with the plurality of identifiers is determined.
